Got the same last weekend. I'm a new user.
Configuration:
Motorola phone + MRA Next connected to Carpuride 702
2 "frozen" items on my Carpuride screen while driving:
- I had to turn left the whole route to the same street. While the voice directions where correct. In example below the 250m sign
- The timestamp for the complete rout was 'frozen'. In example the 17:06 en 1hrs, 123 km

I could not reset it. Even when powered of (after small break) it was still frozen.
I tried to load and ride the track instead of the route, but no difference. I strated both of them by phone...
What can I do to help you reproduce and debug the issue?
